Status-page subscribers

Email addresses subscribed to status.driftstack.dev incident notifications. Confirmed subscribers receive emails when public incidents are posted or resolved (V-295c3-followup fan-out). Force-unsubscribe writes admin_audit_log via V-281 dual-write.

Subscribers list paginated server-side (default 50 per page; ?limit=&offset= query params for paging). Confirmed-and-still-subscribed rows trigger fan-out emails on public incident state changes (V-295c3-followup). Tombstoned rows (90d post-unsubscribe via V-295c3-tombstone purge cron) appear with email = null.
